I don't have any kids.
However, bad language will be the least of my worries when I do have them.
Racist or homophobic language will NOT be tolerated or taught, but I am not going to be upset if my kid says "shit."
Honestly, I find the kids who go "oooh, that's a bad word," ten times more obnoxious anyway, especially if it's really NOT a bad word, like pee or poo.
